Description
본 고안은 수소엔진에 공급하는 수소연료를 저장하고 있는 수소연료 저장탱크의 가열수 순환 가열장치에 관한 것이다.The present invention relates to a heating water circulation heating apparatus of a hydrogen fuel storage tank storing hydrogen fuel supplied to a hydrogen engine.
수소엔진에 사용되는 수소연료는 수소저장 합금속에 저장되어 있으며 수소저장 합금을 일정온도로 가열시켜 유지시켜 주면 수소가 발생되어지도록 되어 있다.Hydrogen fuel used in the hydrogen engine is stored in the hydrogen storage alloy and hydrogen is generated when the hydrogen storage alloy is heated and maintained at a constant temperature.
이에따라 수소연료저장탱크(2)는 제 2 도에 도시하는 것과 같이 수소발생을 위한 가열수단으로 엔진의 냉각시스템에 연결하여 순환하는 냉각수로부터 필요로 하는 온도를 얻고 있다.Accordingly, the hydrogen fuel storage tank 2 obtains the required temperature from the cooling water circulated by connecting to the cooling system of the engine as a heating means for generating hydrogen as shown in FIG.
즉, 엔진냉각수의 온도는 80℃이상인데 반하여 수소발생에 요구되는 수소연료저장탱크(2)내의 온도 조건은 60℃ 정도이기 때문에 냉각수를 열원으로 사용하는 것이다.In other words, the temperature of the engine coolant is 80 ° C. or higher, whereas the temperature condition in the hydrogen fuel storage tank 2 required for hydrogen generation is about 60 ° C., so that the coolant is used as the heat source.
그러나 수소연료저장탱크(2)를 가열시키기 위해 냉각수를 탱크로 순환시키게 될 경우 엔진(1)에 의해 구동되는 워터펌프(3)의 용량 부족으로 냉각수가 잘 순환되지 않아 엔진이 과열될 위험성이 있게 된다.However, if the coolant is circulated to the tank to heat the hydrogen fuel storage tank 2, the coolant may not circulate well due to insufficient capacity of the water pump 3 driven by the engine 1, thereby causing the engine to overheat. do.
이는 워터펌프가 엔진의 회전력의 일부를 이용하고 있기 때문에 워터펌프의 용량을 증대시킬 경우 엔진 출력이 저하되기 때문에 워터펌프(3)의 용량이 한계를 가질수 밖에 없는 데 기인하기 때문이다.This is because the water pump is using a part of the rotational force of the engine, because the capacity of the water pump 3 has a limit because the engine output is lowered when the capacity of the water pump is increased.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 것은 엔진 워터펌프의 용량 부족으로 냉각수 순환이 원활하지 아니하여 엔진의 과열이 초래되는 것을 방지하고 수소연료저장탱크에의 가열수의 원활한 순환이 보장되는 수소연료저장탱크의 가열수 순환가열장치를 제공하는 데 있다.Therefore, the present invention has been proposed in view of the above problems, and its purpose is to prevent the overheating of the engine due to insufficient capacity of the engine water pump and to prevent the overheating of the engine. It is to provide a heating water circulation heating device of the hydrogen fuel storage tank to ensure a smooth circulation.
상기한 목적을 달성하기 위하여 본 고안은 워터펌프에 의해 순환되는 엔진냉각수를 수소연료 발생을 위한 가열수로 이용하여 수소연료저장탱크를 가열하는 수소엔진의 가열수 순환가열장치에 있어서, 엔진으로부터 수소연료저장탱크로 접속되는 가열수 공급라인으로부터 분기접속되어 라디에이터측으로 가열수를 바이패스시키는 바이패스라인과, 상기 바이패스라인을 개폐하는 솔레노이드밸브와, 상기 수소연료저장탱크를 순환한 가열수를 라디에이터측으로 귀환시키는 복귀라인상에 설치된 모터펌프와, 상기 수소연료저장탱크내의 압력을 검출하는 압력센서와, 상기 압력센서로부터 검출된 수소연료저장탱크내의 압력이 상한 한계치보다 높을 경우에는 상기 솔레노이드밸브가 개방되도록 제어하며 하한 한계치 이하인 경우에는 솔레노이드밸브를 폐쇄하고 상기 모터펌프가 구동되도록 제어하는 전자제어장치와를 포함하여 구성되는 것을 특징으로 한다.In order to achieve the above object, the present invention is to provide a hydrogen water storage tank using the engine cooling water circulated by the water pump as the heating water for hydrogen fuel generation in the heating water circulation heater of the hydrogen engine, hydrogen from the engine A radiator is connected to a bypass line which is diverged from the heated water supply line connected to the fuel storage tank to bypass the heated water to the radiator, a solenoid valve for opening and closing the bypass line, and heated water circulated through the hydrogen fuel storage tank.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
제 1 도는 본 고안에 의한 수소엔진의 수소연료저장탱크의 가열수 순환 가열장치를 나타내는 도면으로 도면중 부호1은 수소엔진이며 엔진(1)에 공급되는 수소연료는 수소연료저장탱크(2)내의 합금 속에 저장되어 있다.1 is a view showing a heating water circulation heating device of a hydrogen fuel storage tank of a hydrogen engine according to the present invention, 1 is a hydrogen engine and the hydrogen fuel supplied to the engine 1 is a hydrogen fuel storage tank (2) It is stored in an alloy.
수소연료저장탱크(2)의 저장합금 속의 수소는 일정온도(50℃∼65℃)로 가열시켜 주어야만 얻을수 있으며 이를 위해 워터펌프(3) 구동에 의해 라디에이터(4)로부터 엔진(1)으로 급송된 냉각수가 엔진(1)을 냉각하고 더워진 다음에는 가열수 공급라인(5)을 따라 수소연료저장탱크(2)를 가열하기 위해 공급된다. 수소연료저장탱크(2)내부를 순환하면서 가열시킨 냉각수는 복귀라인(6)을 통해 라디에이터(4)측으로 귀환하게 된다.Hydrogen in the storage alloy of the hydrogen fuel storage tank (2) can be obtained only by heating to a constant temperature (50 ℃ ~ 65 ℃) for this purpose, the water pump (3) is fed from the radiator (4) to the engine (1) After the coolant cools and warms the engine 1, it is supplied to heat the hydrogen fuel storage tank 2 along the heated water supply line 5. The cooling water heated while circulating inside the hydrogen fuel storage tank 2 is returned to the radiator 4 through the return line 6.
상기 가열수공급라인(5)과 복귀라인(6)은 바이패스라인(7)으로 접속되어 있으며 바이패스라인(7)의 도중에는 솔레노이드밸브(8)가 마련되어 있다.The heating water supply line 5 and the return line 6 are connected to the bypass line 7, and a solenoid valve 8 is provided in the middle of the bypass line 7.
그리고 복귀라인(7)에는 가열수를 급송하기 위한 모터펌프(9)가 설치되어 있다.The return line 7 is provided with a motor pump 9 for feeding the heated water.
이와같은 본 고안은 압력센서(10)로부터 검출된 수소연료저장탱크(2)내의 연료압력이 상한 한계치보다 높으면 전자제어장치(11)가 신호를 출력하여 릴레이(12)를 차단하여 모터펌프(9)의 구동을 정지하고 솔레노이드밸브(8)에 전원을 공급하여 바이패스라인(7)을 개방시킨다.The present invention as described above, if the fuel pressure in the hydrogen fuel storage tank (2) detected from the pressure sensor 10 is higher than the upper limit, the electronic control device 11 outputs a signal to block the relay 12 to the motor pump 9 ), The bypass line (7) is opened by supplying power to the solenoid valve (8).
이에따라 복귀라인(6)이 정지된 모터핌프(9)에 의해 차단되었으므로 가열수공급라인(5)을 통해 수소연료저장탱크(2)로 가는 가열수 공급은 중단되고 대신 바이패스라인(7)을 통해 가열수가 라디에이터(4)로 곧바로 순환하게 되므로써 수소연료저장탱크(2)가 과열되는 것을 방지한다.Accordingly, since the return line 6 is interrupted by the stopped motor pimp 9, the supply of the hot water to the hydrogen fuel storage tank 2 through the hot water supply line 5 is stopped and the bypass line 7 is instead replaced. The heating water is circulated directly to the radiator (4) to prevent the hydrogen fuel storage tank (2) from overheating.
그러나 만일 압력센서(10)로부터 검출된 탱크(2)내의 압력이 하한한계치 이하일 경우 수소연료공급이 원활치 못하게 되므로 이때에는 전자제어장치(11)가 솔레노이드밸브(8)에 전원공급을 차단하여 바이패스공급라인(7)을 폐쇄하고 릴레이(12)를 접속시켜 모터펌프(9)를 구동한다.However, if the pressure in the tank 2 detected from the pressure sensor 10 is lower than the lower limit, hydrogen fuel supply is not smooth. At this time, the electronic controller 11 cuts off the power supply to the solenoid valve 8 and bypasses it. The supply line 7 is closed and the relay 12 is connected to drive the motor pump 9.
이때 워터펌프(3)와 모터펌프(9)의 펌핑 능력이 크게 차이나게 될 경우 중간라인에 부압이 형성되는 것을 방지하기 위하여 rpm센서(13)로부터 엔진 회전수를 검출하여 rpm에 비례하는 구동 듀티신호를 출력하므로서 모터폄프(9)의 회전속도를 제어한다.At this time, when the pumping capability of the water pump 3 and the motor pump 9 is greatly different, the driving duty is detected in the engine speed from the rpm sensor 13 to prevent negative pressure from being formed in the middle line. The rotation speed of the motor pump 9 is controlled by outputting a signal.
이에따라 엔진을 통하여 나온 뜨거운 냉각수(가열수)가 수소연료저장탱크(2)를 순환하면서 가열하여 수소연료 발생량을 증대시켜 적정압이 유지되도록 하는 것이다.Accordingly, the hot coolant (heating water) from the engine is heated while circulating the hydrogen fuel storage tank 2 to increase the amount of hydrogen fuel generated so that the appropriate pressure is maintained.
이상과 같은 본 고안에 의하면 워터핌프의 펌핑 용량부족을 해결하여 엔진이 과열되는 것을 방지하고 수소연료저장탱크를 효율적으로 가열하여 가열수가 원활하게 순환하게 되는 효과가 있다.According to the present invention as described above to solve the lack of pumping capacity of the waterpump to prevent the engine from overheating and to efficiently heat the hydrogen fuel storage tank there is an effect that the heated water is circulated smoothly.
